HYDROCARBON-VAPOR BURNER.

SPECIFICATION forming part of Letters Patent No. 316,385, dated April21, 1885.

Application led May 16, 1884.

To @ZZ whom it may concern:

Be it known that we, GAEsoN MYEEs and J. BENNETT WALLACE, of Chicago, inthe county of Cook and State of Illinois, have invented certain new anduseful Improvements in Hydrocarbon-Vapor Burners; and we do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to means for opening and closing the needle-valveof a hydrocarbonvapor burner, and has for its objects, first, to providea construction in which the movements of the said needle-valve areproperly limited, and, second, to afford anindication to the eye of thecondition of the needle-valve as to whether it is closed or partially orwholly open.

The invention consists in the several matters hereinafter described, andpointed out in the claims.

In the accompanying drawings, Figure l is a perspective view of a burnerprovided with our improvement. Fig. 2 is a central Vertical section ofthe view shown in Fig. 1. Fig. 3 is a plan view of the hand-wheelapplied to f the valve-shaft.

A represents a perforated burner proper,

of which A is the base-plate; A2, the perforated cap, and A3 theinduction-tube by which the vapor is directed into theV interior of theburner A.

B is a deflector by which the"flame may be directed against the partsgiving passage to the liquid or vapor for the purpose of keeping themheated up to generating heat when the burner is not in active use.

G is a liquid and vapor pipe connected with asuitable source ofliquid-hydrocarbonsupply.

D is apipe leading downward from the upper end of the pipe C to a pointopposite the opening of the induction-tube Ai. At this point the pipe Dis provided with a needlevalve openingv arranged to admit the vaporcentrally into said tube A3.

D is a tubular projection forming the support of the needle-valve.

Eis the needle-valve shaft having its point e itted to the opening inthe tube D in the (No model.)

usual way. Said valve-shaft is provided with a screw-thread of rapidgain or high pitch fitted to a corresponding thread in the tube D', sothat only a partial revolution of the said valve-shaft will eithersufficiently open or tightly close the opening e for all purposes of theburner. The shaft E .protrudes duly beyond the tube D', and the passageabout the said shaft is closed to prevent the escape of liquid by anysuitable cap, E2, and packing or other appropriate means. Inthe presentinstance a plate, e, surrounds the shaft and is shouldered in the loweror outer end of the tube D', and lbetween said plate and the screwcap E2any suitable packing, e2, is inclosed.

To the outer or lower end of the shaft E is adjustably secured ahand-wheel, F, which is much larger than those heretofore commonlyattached to the stem or shaft of the needlevalve, and which, as hereshown, embraces within itsrim the vertical pipe C. This pipe l C thusmay serve as a stop to arrest or limit the rotation of the hand-wheeland valve-shaft by striking the arms of said hand-wheel. A four-threadscrew, twenty-four threads to the inch, is found to be rapid enough togive all necessary movement to the valve with such a partial rotation ofthe hand-wheel as is easily practicable in the construction described.

The wheel-rim is supported from the hub by arms which, as here shown,are two in number, and are both located on one side of the diameter. Thetube C passes through the larger space and, taking the diameter of thesaid tube into account, the wheel and the valve-shaft have about orlittle more than onehalf of a full rotation.

On the rim of the wheel are preferably cast The wheel is secured adjustably to the valve- A shaft by means of a set-screw, f. To properlyapply the wheel F to the valve-shaft, the wheel is detached and thevalve is tightly closed by aid of pliers or other means. The shaft E isthen inserted in the wheel-hub with the arm adjacent to the word Shut incontact with or near the tube C, and the set-screw f is tightened. Therotation of the wheel to bring IOO the other wheel-arm toward or againstthe tube C therefore opens the valve. When the valve Wears, the Wheelmay be readj usted as may be required.

A part ofthe wheel-rim may be broken away, if desired, (as by theremoval of a part, f2, Fig. 8, extending, say from f3tof*,) to adrnitthe tube C; but We prefer the present construction, which, of course,requires the tube to be inserted through the Wheel before said tube isfinally connected.

The novel features in the deiiecting devices herein lshown form thesubject of another application for patent, Serial No. 130,718, iled May8, 1884, by J. B. Wallace, one of the present applicants.

We claim as ourinvention- 1. The combination of the needle-valve havingon its shaft a quick orhigh pitched screwthread, a wheel adj ustablysecured to the valve-shaft, and a neighboring stationary part of theapparatus engaging the Wheel, substantially as described.

2. The combination, with the stationary liquid-pipe, and the neighboringneedle-valve 2 5 provided with ahigh-pitched screw-thread, of a wheeladjustably secured to the valve-shaft and embracing the liquid-tube,substantially as described.

3. The combination, with the stationary 3o liquid-pipe, and neighboringvalve-shaft provided with a high-pitched screw-thread, of a Wheel, F,having an open space embracing said liquid pipe and bearing the WordsOpen77 and Shut, or their equivalents, 3 5 substantially as and for thepurpose set forth.

In testimony that We claim the foregoing as our invention We affix oursignatures in presence of two Witnesses.
